Summary
Systemic lupus erythematosus (SLE) can lead to hypertrophic cardiomyopathy, a rare heart condition. This case highlights a potential, seldom-documented cardiac complication of SLE.
Area of Science:
- Cardiology
- Rheumatology
- Internal Medicine
Background:
- Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with diverse clinical manifestations.
- Cardiac involvement in SLE can range from pericarditis to myocarditis, but hypertrophic cardiomyopathy is exceptionally rare.
Observation:
- A 45-year-old woman with known SLE presented with new-onset clinical and echocardiographic findings suggestive of hypertrophic cardiomyopathy.
- The patient had no prior history of hypertension, valvular heart disease, or family history of cardiomyopathy or sudden cardiac death.
Findings:
- Echocardiography confirmed the presence of hypertrophic cardiomyopathy in the SLE patient.
- This represents a rare association, with only two prior reported cases linking SLE and hypertrophic cardiomyopathy.
Implications:
- This case underscores the importance of considering cardiac complications, including hypertrophic cardiomyopathy, in SLE patients.
- Further research may be warranted to elucidate the mechanisms and prevalence of this rare SLE-related cardiac manifestation.
